Vista - Help on my vga card

My Standard Vga Graphics Adapter is not detected on my laptop how can i change it???

Try going into BIOS and check out the settings. I don't know what type of machine/laptop you are using or what type of graphics card you are running but checking out the Bios is a sure way to find out what you machine is set to.
Hope this helps?
P.S. To enter Bios is not the same on every machine could be holding down the Ctrl key and constantly hitting the Del key will let you in but there are quite a few F12, F2 and so on. Look at your post screen as it will tell you how you can enter Bios on your machine.

my machine/laptop is Sharp-Pc-AL70J when i press ctrl key and then press del it not works and also when i hit f12 or f2 nothing works i dnt have any vga carp its only a standard video card but when i view the standard vga card it said that its not detected but its already installed

get in touch with the supplier for support and call the manufacturer or send it back to the manufacturer for this, a collegue of mine had a similar problem and thay ended up replacing the laptop as it was a hardware failure, on laptops the parts can't be replaced (usually). pc's are easier to problem solve as parts can be replaced with ease laptops however are not designed that way.

assuming it's a new laptop and still under warranty call them and go through it with them, they will either solve or send you a new one under the conditions of the warranty.

sorry cause my laptop is old this is a gift for my aunt.. ^^
